DGX Hi-Viz Polyester Line

Custom manufactured for Dive Gear Express, our famous DGX Hi-Viz Polyester Line is high-tenacity abrasion and UV resistant line that also resists twisting or kinking and has minimal stretch. The line has negative buoyancy in both fresh and salt water. Traditional white nylon line used on reels is difficult to see in open water, but our Blaze Orange and Fluorescent Chartreuse colors stand out, allowing easier line management with nearby divers. The durable colors of our Hi-Viz line also remains the vibrant over time, unlike the "wash-out" fading typical of ordinary nylon cave line that has been dyed orange.

Our Glow-in-the-Dark White color has been impregnated with phosphorescent pigments. The phosphorescent pigments give the line the ability to absorb light and then slowly emit this absorbed light for a period of time. Due to this phosphorescent property the line can "glow-in-the-dark". The emitting time and brightness of the line varies widely and depends upon a variety of factors including the amount of light previously absorbed, visual acuity of the diver, distance from the phosphorescence and amount of surrounding light. You can see in the "More Views" a photo of our Hi-Viz Glow-in-the-Dark White next to our White Ultra-Viz line, which does not have this GITD property. We shone our DGX 600 handheld light on the line for about 20 seconds, then turned the light off and took the photo in a darkened room without a flash. Note that the "glow" is so bright that it is reflected on the spool next to it. The "glow" has not been enhanced post production. For this test the really bright "glow" lasted several minutes then slowly faded. Please notice the GITD White color is more expensive than the Blaze Orange and Fluorescent Chartreuse color.

The technical specification for the diameter of our DGX Hi-Viz line is approximately 1.8 mm which does not fit nicely into the archaic 'twine' size code numbers that might be familiar to long time cave divers. Describing the diameter using size codes, the 1.8  line falls somewhere between #21 and #24. Regardless, the 1.8 mm polyester line in water is stronger than #36 nylon and thinner than #24 nylon so you will be able to load plenty of extra on the reel.
